| Material Notes | Acetylgalactosamine is an important constituent of brain heteropolysaccharides (glycoproteins). The concentration of the N-acetylgalactosamine-containing glycoproteins in the 3-year-old cerebral gray matter from human brain is 7-15 times greater than in 8-year old tissue and 15-30 times greater than in 72-year-old tissue. (PMID 1207868) Acetylgalactosamine patterns of the composition of the soluble glycoproteins from endoscopic mucosal biopsies tends to decrease in the tumor area in cancer of the stomach (compared with the antrum and corpus of control stomachs). (PMID: 7151277) Chondroitin 6-sulfotransferase (C6ST) is the key enzyme in the biosynthesis of chondroitin 6-sulfate, a glycosaminoglycan implicated in chondrogenesis, neoplasia, atherosclerosis, and other processes. C6ST catalyzes the transfer of sulfate from 3'-phosphoadenosine 5'-phosphosulfate to carbon 6 of the N- Acetylgalactosamine residues of chondroitin. (PMID: 9639683) [HMDB] N-Acetyl-b-D-galactosamine is an oligosaccharide residue found in the lining and glandular epithelium, the stroma and the vessels (capillary and large vessels of the human postmenopausal endometrium. (PMID: 8930627) It is suspected that N-Acetyl-b-D-galactosamine is a molecule that binds to IgA in the glomerular mesangium in Henoch-Schoenlein purpura associated nephropathy (the most common vasculitis of childhood).
